What and why
Apps in Copilot Cowork are now available through the Frontier program, and Apps in Microsoft Copilot Studio are rolling out in public preview.To provide a unified experience for building apps with natural language, Microsoft is retiring the App Builder agent in Microsoft 365 Copilot and vibe.powerapps.com.
Copilot Cowork and Microsoft Copilot Studio will become the primary experiences for creating apps using natural language. This retirement helps consolidate app creation experiences and provides makers with a consistent path forward for building and managing apps.
